To make it work at the new price range, they need to find Talulah quality girls who come in once or twice a fortnight. They will need rave reviews to give guys confidence to spend money.
That's a huge number of new good looking, brassy girls for them to find soon ish. I reckon it will kill off the chubby average looking ones quite soon. The Ophelias will still be able to pull guys in.
Look at Diva. The vast majority of them are Russian and Romanian girls prepared to show unblurred face pictures which prove that they are good looking.
If they are not on holiday, they might be available for many days, not on a rota now and again.
Diva girls may experience lots of down time due to the price, it's impossible to tell.
